1. An image processing apparatus coupled to a plurality of image capturing devices collectively configured to generate a multi-view image and reduce a noise in an epi-polar image while generating a three-dimensional image from the multi-view image,
wherein the image processing apparatus is configured to:
divide the multi-view image into a flat region and a non-flat region,
generate the epi-polar image from the multi-view image,
replace an epi-polar line in the epi-polar image corresponding to the flat region with an average pixel value of the multi-view image, and
replace an epi-polar line in the epi-polar image corresponding to the non-flat region with a pixel value of a center-view image obtained from a centrally located image capturing device among the plurality of image capturing devices.
